Hi, Jennifer.
I don't quite agree that this is relevant for Polk support as this is just a question of which IR signal are sent by the remote. There are no other protocols involved. As long as the Chromecast Voice Remote is programmed to send the correct IR signal to the soundbar, the soundbar will respond correctly.
When I compare the IR signals sent by the original remote with the signal from Chromecast Voice Remote, the codes are "wildly" different, so this issue can probably be solved by adding the correct codes to the firmware. I will, however contact Polk support in parallel to see if this is an issue they are aware of.
Below, I have added the IR codes sent for volume up from Chromecast and Polk remotes.
